So it's time to remember the Blender Conf 2013, with videos of my presentations of QUIPCAM and MYLA.

The Blender conf is really nice, with a lot of very interesting prestenations.
Blender is near everywhere, so there is presentation about near all CG subject, from game to VFX, via real time vizualisation, shading, OSL (of course!), and a lot more!

Here is the first presentation about QUICKCAM. Beginning is missing due to a technical problem:

To celebrate Chaosgroup VRay entering the OSL world, with it's 3.0 version, here is a Three Ambient Occlusion for the price of One !

This shader is an Ambient Occlusion, but it does what a lot of you already do by hand: put 3 different AO, each on a different color channel.

Then, you just have to sepparate RGB channels with you favorite compositing software. The main advantage of this shader is that it optimaze rendering time by do not triple shading.

There is two versions of the shader :TriGAOVr.osl : it's 100% Vray 3.0 compliant version !

and

TriGAO.osl : this version is for renderer implementing the 'getmessage' OSL functionnality, like Cycles or SpectraStudio.
It is about 30% faster, as it tracing just one ray for the three AO. It has a smoother AO gradient, needing less AntiAlias.
